Too Zti Li HJZ/ H nmg concern:

Be it known that we, HAMLIN L. SHUTE and llanmft. .lLlEX-SCHEN, citizens of the United States, residing at indianapolis, in the county oi Marion and State of Indiana, have invented new and useful Improvements in paratus for Illolding Concrete W'alls; and we do declare the following to be a full, clear. and exact description of the invention, reference being had to the accompanying drawings, and to the let-.

ters and figures of reference marked thereon, which form a partof this specification.

This invention reiatesto the construction of continuous molded walls, piers, columns, and. like structures formed of concrete composition', and-tho invention has particular refer:

once to the molding-forms and the couplings therefor and to the supports and the gages for the forms. the object of the invention being to provide improved apparatus and appl ances that may be used expeditiously and economica-Hy in the construction of structures of the character indicated;

' iiith theabove-mentioned and ot er ohicc ts in view the; invention consists in improved TllOlCl'fOl'iIlS, couplers, for the forms, supports and gages for the forms, and cou gilings for connecting the sections of the forms together; and the invention consists also in improved cores andappliances for forming hollow walls. The invention consists, further, in the parts andNt-hecombinations and arrangements of part. hereinafter particularly described and claimed.

deferring to the drawings, Figure l is a fraguientary perspective view of parts of the apparatus undhppliances in. operative positions in' connection with'a concrete wall under construction; Fig. a fragn'ientary top plan of tuocOnneCted' plane mold-forms; Fig. 3, a fragmentary front elevation of two connected pla'ne'forins; Fig. d, a'i rcgrnentary' top plan Fig. T, a side elevationof the end coupling; 7

Similar reference characters in the several figures of the drawings designate corresponding elements or features.

In construction the mold-forms are composed of wooden planks provided with metallic devices whereby they may be connected together by means of couplers and alsoprovided with matching devices and other appliances to be hereinafter described. Thet'orms A, A, A, A, A, and A are designed to he used to form the outer sides of corner-Walls, the forces A, A, A, A, and A being adapted to also be used to form the inner sides of cornor-walls, and the forms A, A, A, A, A

and A" are for use in forming the inner sides of corner-walls. The forms A, A A, A", A and A are designed for forming straight or plane faces of walls.

The couplers forco'nnecting the ends of the forms together each include a pair of identical lug-plates B, that are secured to the outer faces of the forms, each plate having a p'air of lugs aand .7) projecting outwardly and'up- Wardly when the form is in operative position. Each lug has an'inner wedge-face disposed toward its supporting-plate. In some cases the, plates B are placed close to the ends of the forms, as at one end of A, A, and A and in" other cases the plates are at a distance from the form end equal to the thickness of the form, as at the opposite end of .A and on The couplers also include de-.

; tachab'le locking-plates for cooperating with when it is being connected to and disconnected the lugs, there being both straight plates and angular plates.

The locking-plates C, comprising detachable parts of the outer corner-couplers, are formed as sections of L-shaped angle-bars,

there being thus two wingsdesigned to co-.

operate with both angles of a. corner. The plate has four slots 'e g 2, the slots having side recesses d f la j, respectively disposed at the farther sides thereof from the corner of the plate to permit of movements of the plate from the lugs. Aboveeach'slot is a wedge k at the outer side of the plateintegral therewith to engage the wedge-faces of the lugs onthepl'ates B. The slots are adapted to receive the lugs which project through the plateswhen in use, as will be seen. a

The locking-plates'D, comprising detachable parts of the inner corner-couplers, are

inform similar to the plates C-in that they are angular and have slots Z n p r to receive the lugs of theplates B, the slots having side recesses m 0 q s, respectively disposed at the nearer sides thereof to the corners of the plates to permit lateral movements of the wings of the plate with respect to the lugs.

Wedges 7c are attached to the plate above the slots to'engage the wedge-faces of the lugs of the plates B.

The locking-plates E, comprising detachable parts of the couplers for the ends of the ,plane molds, are each formed as a flat plate notched at it's corners and'provided with slots of the forms, as A AA A A each plate 'ex-,

tendingfro iijthe bottom'of the form beyond the tdptliereof and having in the lower end thereof a slot 1, andin the upper endther'edfa slot 2 deeperf'than the slot 1, the "pro:

,jecting upper end of the plate' forminggagefingers 3 and 4, against wh ch a form may bear to insure matchingof the forms one iipon'another," the inner faces of the'fi'ngers being in the same plane as the outerfaces of the formsf In the edges of the forms are notches'5 opposite-the slots 1 and 2.

Gage-barsG are employedfor preventing the forms'from spreading, and in the present case the bars are designed foruse in thick walls,- being tapering both in width and 'to freely admit'thebars G.

,for' lifting thecore from the concrete.

order to prevent the concrete from adhering height, so as to be easily driven walls aft-er removal of the forms. Each bar"- has anumber of pin-holes 6 near the smaller 1 end thereof and is provided with, a head 7 at l" the larger end" thereof, pins 8 being inserted in holes 6, the holes being so -"arranged'as toserve as gages for walls of difi'erent thickmasses. The slots 1 and 2 are sufliciently large When hollow walls are cores are employed, which maybe either circular or oblong'in plan, each core comprising a shell H or H to which a top 9 is secured,'a hook .10 being attached to the top In to the core and rendering'its withdrawal difli- I desired, suitable cut, sleeves I are employed to cover the,coreshell and remain'as' linings in the openings madeby the cores. The cores are very slightly tapering, (not shown.) s much-would beobjectionable, and ordinarily they would stick to the concrete. The sleeves are preferably composed of cheap strawboard or tarpaper and permit the cores to be readily withdrawn therefrom, while the sleeves adhere" as linings in the openings and may later be removed therefrom or left to perish in the course of time. 'Smallwire bars 11 are laid onthe wall courses for supporting the cores and sleeves temporarily while filling in the concrete about the cores, the barsusually being allowed toremain, although they may be bent and removed, if desired.

' The extensible mold-forms, as A and A, areprovided with removable filling-plates J andK, respectively, the inner sides of the forms being suitably recessed to receive the plates as well as the extension-plates L and and M, which are substituted for thefillingplates,v as on forms A and A", when the wall is to be narrowed .at the top of a'story., The forms have horizontally-disposed slots 12 and 13, in which are bolts 14 and 15 for securing the plates to the forms. Each plate L and M hasbolt-holes ldand 17 to reeeivethe bolts, and it is provided with integral lugs 11 and b to be engaged by theplate vD. 'hen the plates L and M are moved out, so as to increase the lengths of the forms, the gaps in the faces of the forms are filled by fillingplates N, having each a pair of studs 18 and and win 19 inserted in the slots 12 and 13 ably secured therein. In practical use, as will be seen in Fig. 1-, the lower course of; concrete has been filled: in the mold-forms upon the foundation, and the next'upper course of forms has been set' on the lower forms ready to be filled with the concrete, after which the lower forms may he removed, the upper -'forms then being supported by the bars G. The plates C, l), and' E may be released by driving them upwardly somewhat, after which they may be lifted from the lugs of the coupler-plates B B. As

wanes plates L and 'M may be further extended to suit a narrower wall, the filling-plates N being thenattached to the forms, as in Fig. 12. In other respects the forms and attachments are used in the ordinary manner.
